Mouse screen interface external control method based on absolute coordinate positioning technology and system thereof

Abstract

The invention provides a mouse screen interface external control system based on absolute coordinate positioning technology. The system comprises an intelligent TV and an air mouse remote controller. An optical positioning module of the air mouse remote controller monitors the relative position of the air mouse remote controller and a reference light source, a coordinate (x,y) is calculated, absolute coordinate information is obtained, and coding information is sent to the intelligent TV through an infrared emission tube of the air mouse remote controller. The invention also provides a mouse screen interface external control method which comprises the steps that the an air mouse remote controller calculates the absolute coordinate information of movement of the air mouse remote controller and sends the absolute coordinate information of the movement /or button information to the intelligent TV, and the intelligent TV carries out decoding on the received absolute coordinate information and/or the button information to realize the related function control. According to the method and the system, the disadvantages of a current air mouse based on relative coordinate technology are overcome, the method and the system have the advantages of high precision, fast response speed, good anti disturbance, a problem that watch content of a user is shielded by an OSD menu is solved, and a good control experience is brought to a user.

Description

technical field [0001] The invention relates to the field of smart TV remote control, in particular to a mouse screen out-of-bounds control method and system based on absolute coordinate positioning technology. Background technique [0002] In the field of home entertainment, as TVs are more and more closely integrated with the Internet, more and more exciting content enters the TV screen, watching high-definition, searching for videos, browsing the web, and even using the TV directly as a computer screen. Family entertainment The center gradually concentrated to the living room. In view of the above user needs, how to conveniently control the TV and bring users a good human-computer interaction experience has become a hot spot of technological development. In this context, the air mouse came into being. The air mouse can operate the screen cursor like a traditional mouse, but it does not need to be placed on any plane, and can be operated by shaking in the air. [0003] A...

AI Technical Summary

Problems solved by technology

[0003] At present, when the product user controls the TV, the corresponding OSD menu will pop up on the screen. The OSD menu is superimposed on the original screen display content, blocking the display content that the user is watching, and affecting the normal viewing of the user.

[0004] On the other hand, existing air mouse products on the market use gyroscope and acceleration sensor modules, based on relative coordinate technology, this technology has the following disadvantages, resulting in poor user experience

[0005] 1. Based on relative coordinate technology, the position of the screen cursor is inconsistent with the pointing position of the user's remote control;

[0006] 2. There is a problem of temperature drift in the gyroscope, and the control accuracy will change with the ambient temperature;

[0007] 3. Gyroscope technology delay phenomenon, there is a time difference between the user moving the remote control and the screen cursor moving
